Alright. The Bianchi holster is very good, especially after the wax paper break in. Unfortunately to take the holster off, you need to take your belt off. Not exactly convenient in certain situations.
I just got a Blackhawk Sportster holster to try as an alternative. Unlike the more expensive Serpa holster, there's no button holding it in place by the trigger guard that could lead to accidental discharges, it's all pure friction. I've got the screw tightened to the point you can flip the holster upside down and shake it, and it'll hold the Glock reliably, but still being easy to draw with a quick tug.
